Replacement Board SBC86807 V2

I'm Having some problems with the MotherBoard in my device, and also having some problems trying to locate the appropriate one online so that i can replace, therefore i am wondering if anyone would have an idea on where i could find (SBC86807 V2) board. I got some results from eBay, but supplier was in China and not sure if this would be reliable, I am looking for a supplier and preferably in the UK/Europe

Thanks..
